Skill UI

A specialized AI agent for product management in the Chinese internet market. It helps prioritize requirements, plan roadmaps, analyze growth and retention metrics, and handle operational issues like project delays. The agent uses silent reasoning to identify core blockages and dominant mechanisms before providing actionable next steps, stop lists, and switching conditions. It focuses on direct, executable advice without unnecessary theoretical explanations or historical references, suitable for product owners and managers facing complex decision-making scenarios.

This skill provides comprehensive methodologies for capturing, analyzing, and documenting network protocols. It is crucial for security researchers, developers ensuring interoperability, and engineers debugging complex network communications by understanding the underlying data exchange mechanisms.

A comprehensive guide for building or reviewing SwiftUI User Interfaces that utilize the modern Liquid Glass aesthetic. This skill focuses on correctly implementing native Apple APIs (like `glassEffect` and `GlassEffectContainer`) while ensuring proper fallback mechanisms, modifier ordering, and performance for iOS 26+ devices. Ideal for adopting cutting-edge iOS design patterns.

This skill validates Three.js graphics implementations using fixed-view visual contracts and diagnostics. It ensures reproducibility through seed sweeps, camera-scale tests, and temporal stability checks. It captures no-post baselines and GPU budgets to prevent regression in procedural scenes, evaluating the rendering mechanism rather than subjective screenshots.

An advanced reliability wrapper for AI agents that monitors, manages, and recovers from tool call failures. It automatically handles common issues such as truncated JSON responses, API timeouts, rate limits, and mid-chain process breakdowns. By implementing sophisticated failure classification, checkpointing, and learning mechanisms, Guardian ensures complex, multi-step agent workflows remain stable and resilient.

This skill generates appropriate user feedback states for components and pages, including loading skeletons, empty states, error messages, and success toasts. It ensures consistent UI presentation by implementing specific design patterns for data-dependent areas, handling partial or full failures, and providing retry mechanisms. It follows design language references for animations and accessibility, suitable for React-based frontend development workflows.

A comprehensive skill for conducting client-side injection vulnerability assessments on web applications. It identifies XSS and HTML injection flaws, demonstrates exploitation techniques for session hijacking and credential theft, and validates input sanitization and output encoding mechanisms. Includes practical examples and strict safety guardrails.
